The ribbed headwall of the 1902 crater cuts most of the SW flank of Santa María volcano. The 1.5-km-wide crater extends from just below the summit down to 2200 m elevation and has a volume of 0.5 cu km. The compound Santiaguito lava dome (left) began growing in the new crater in 1922. This 1991 view shows a blocky lava flow descending the right flank of Santiaguito.
